True. The Hobbit never had Bard helping those Dwarves, and there was not n epic battle in Dale. Or at least what remained of it.
Or the inclusion of Radagast (whose one tiny part was left out of LOTR) and his rabbits
Or Azog, who was killed at Moria, suddenly alive and revengeful
Or Tauriel and the unbelievable love story between her and a dwarf
Or the whole scene between Smaug and the dwarves inside Erebor
Don't get me wrong, it's fun to watch, but it's a far departure from The Hobbit.
